ROTARY GEAR-RING HEATER.

Application filed May 13,

This invention relates to rotary ring gear heaters. i

The general object of the invention is to provide a novel and efiicient rotary burner which may he used for heating and expanding ring gears.

A specific object of the invention is to provide a table having a rotary burner thereon and having novel means for directing the flame againts a circular article disposed on the table.

Other objects of the invention will be apparent from the following description taken in connection with the accompanying drawings wherein:

Fig. 1 is a side elevation partly in section showing our invention;

Fig. 2 is a top plan view showing our invention;

Fig. 3 is a sectional view on line 3-3, Fig. 2 showing the operating parts;

Fig. 4: is fragmentary perspective view of one of the burner elements, and

Fig. 5 is a section on line 55, of Fig. 4.

Referring to the drawing by reference characters, we have shown a standard at 10. This standard is provided with a base 11. The standard supports a table 12 which is secured thereto by means of a coupling member 14. The table 12 is provided with a central cavity in which a post 15 is fitted to rotate on an anti-friction member 16.

The post 15 is provided with a central channel 17 and with a transverse channel 18 which places the central channel in communication with a recess 19 in the outer face of the post. This recess 19 communicates through passages 20 at 21 with a pipe 22 which is connected to a gas pipe 23. A valve 24; controls communication through the pipe 22.

The pipe 23 is connected by a pipe 25 with a discharge orifice 26 which serves as a pilot for the burner to be presently described. The pipe 25 is provided with a valve 27 which controls communication therethrough.

The post 15 is provided with a cap member 30 thereon and this cap member is provided with a plurality of hollow curved arms 31 which are in communication through apertures 32 with the channel 17. Each of these curved arms 31 is provided at its extremity 32 with a lateral discharge opening 33 and a lower discharge opening 34. The cap 30 is also provided with transverse rod through the arms 31.

35 on which are mounted a pair of vanes 36 which are adapted. to be shifted to change their angular position and which may be held in set position by means of thumb nuts 37. i

In operating our device the gas is turned on at the valve 38 and the pilot valve 27 is adjusted and the pilot- 26 lighted. A ring gear or other article to be heated, as shown at 39 is placed on the table 12 and the valve 241 is opened allowing gas to pass through the channels 21, 20, 19, 18, 17, 32 and to and The gas issues in the lateral opening 33 and at the bottom opening 34 and is ignited by the pilot 26. The burning gas issuing from the lateral opening 33 causes the arms 31 to revolve while the gas issuing at 34 strikes the ring gear 39 and heats this gear.

The deflectors 36 are set at the desired angle so that the flame will strike them to increase the speed of rotation. By shifting the vanes the speed maybe varied. In order to adjust the vanes 36 the thumb nuts 37 are turned to the desired position, this done the thumb nuts 37 are tightened so that the vanes will beheld in the set position.

From the foregoing description it will be apparent that we have provided an improved rotary heater which can be economically manufactured and which is highly efiicient in use.

Having thus described our invention, we claim:

1. A ring gear heater comprising a support, a rotary arm mounted on said support, a burner on said arm, said burner having a laterally and a downwardly directed port therein, and means to lead gas to said ports.

2. A rotary burner comprising a table, a plurality of rotary arms mounted on said table, said arms having burners thereon and deflectors associated with said arms.

3. A rotary burner comprising a table, an arm mounted to rotate on said table, said arm including means for conducting gas, a burner on said arm in communication with said means and means to connect said first mentioned means with a gas supply.

at. A rotary burner comprising a base member, a table thereon, a rotary member mounted upon said table, a channel in said member, means to lead gas to said channel, and a plurality of rotary arms connected to said member, each of said arms being hollow and having a cavity therein communicating with said channel said arms having burners thereon.

5. A rotary burner comp-rising a base member, a table thereon, a rotary member mounted in said table, a channel in said member, means to lead gas to said channel, a plurality of arms connected to said member, said arms each being hollow and hav ing a burner thereon, a cap carried by said member, said cap having a laterally extending rod thereon, and a shiftable deflector mounted on said last mentioned rod.

6. A rotary burner comprising a base member, a table thereon, a rotary member mounted on said table, a channel in said member, means to lead gas to said channel, a plurality of rotary arms connected to said member, each of said arms being hollow and having an aperture communicating with said cap communicating with said top transverse channel, said arms being hollow, said arms each having a discharge orifice therein.

8. In a rotary heater, a table, a post rotatable on said table, said post having a channel therein, arms mounted on said post and communicating with said channel, said arms being hollow, said arms each having a discharge orifice therein, a transverse rod adjacent to said arms and adjustable vanes mounted on said transverse rod.

9. In a rotary heater, a table, having a cavity therein, a post in said cavity, said post having a longitudinal channel therein, transverse channels at the top and bottom of said post, said table having channels therein communicating with the bottom transverse channels, a cap on said post, arms on said cap communicating with said top transverse channel, said arms being hollow, said arms each having two discharge ori' lices therein, one of said orifices being directed downwardly and one laterally, a transverse rod mounted on said head and adjustable vanes mounted on said transverse rod.

In testimony whereof, we hereunto aliix our signatures.
